Applicability of Berry's index in bite mark analysis

Area of Science:

• Forensic Odontology
• Anthropometry
• Dental Forensics

Background:

• Bite mark analysis is crucial in forensic investigations.
• Accurate bite analysis relies on precise measurements and established correlations.
• Facial proportions can provide supplementary data for bite analysis.

Purpose of the Study:

• To evaluate the utility of Berry's Index as an adjunct in bite analysis.
• To determine the correlation between upper central incisor width and bizygomatic width.
• To assess the applicability of Berry's Index in forensic odontology.

Main Methods:

• Study involved 100 dental students (50 male, 50 female) aged 18-30.
• Measurements of upper central incisor width and bizygomatic width were recorded.
• Data analyzed using SPSS, employing Pearson correlation coefficient.

Main Results:

• A good positive correlation (r=0.613) was observed between upper central incisor width and bizygomatic width.
• Females showed a stronger correlation (r=0.678) than males (r=0.525).
• Mean upper central incisor width: 0.7602 cm (male), 0.7765 cm (female).

Conclusions:

• Berry's Index serves as a useful adjuvant for bite analysis.
• It aids in determining facial proportions from central incisor width.
• The index demonstrates potential for enhancing forensic odontology techniques.
